ZF-3362: about BCC and TO in Zend_Mail_Transport_Sendmail
$mail->addTo('firstname.lastname@example.org'); $mail->addBcc('email@example.com'); $mail->addBcc('firstname.lastname@example.org');
The above code snippet adds all three mail addresses to the TO field. $mail is an instance of Zend_Mail. I would expect the latter two to be added to BCC field.
I am using standard/trunk from svn at the time 1.5.2 is released.
NOTE: Applies to using IIS under VISTA with no explicit mail transport set.
